AT&T has yet another thing to gloat about - besides being able to talk on the phone and surf the web at the same time. The iPhone 4S uses HSPA+ on the AT&T GSM network at speeds of 14.4Mb/s. On Verizon and Sprint - CDMA networks, the iPhone 4S will only achieve download speeds of the iPhone 4's top speed; 7.2Mb/s.

The current lineup of Carriers leaves you with three choices - AT&T, Verizon, and Sprint. The only GSM option is AT&T because T-Mobile bowed out and chose not to support the iPhone in favor of seeing a future in Android devices. If you're wanting the best value out of your network, you may want the unlimited data option from Sprint. Just remember to consider that AT&T will be the only network capable of benefiting from the speed boost from the iPhone 4S's dual antenna system.

Currently, the speed boost advantage of the iPhone 4S on a 3G network is capable of 4G speeds. Many are disappointed that the iPhone 4S doesn't support 4G, although 4G is a battery sore. I highly suggest this option over 4G simply because you will get comparable speeds and keep the mature battery life of 3G. The only difference is that you will not have a, "4G" icon in the top left of your status bar next to your carrier name. I'm sure they will develop (or have developed) a jailbreak tweak that you can trick yourself into feeling you have 4G, though.

7.2 Mbps on EV-DO Rev. A?! Come on people (especially Anthony Bouchard), get a clue!The Gizmodo article said nothing of the sort. It only stated that the speed wouldn't change versus the same speed of the iPhone 4 on Verizon [which is EV-DO Rev. A]. Results

Meanwhile, Verizon and Sprint's iPhone 4Ses still run on CDMA, which offers the same speed as the iPhone 4. If you want the download speed boost, it seems that the only option is AT&T.

Those numbers came from Apple. You probably won't get those speeds in real-life situations due to bandwidth and signal - however the the keywords that Apple said were, "up to."

Ok here's my situation. I have a 3GS on AT&T and my contract is up. I live in Long Island, NY where the AT&T service is good but work at JFK Airport where the service isn't so good and I will be grandfathered for unlimited data and the $10/1000 mms plan (I think at least) When I get the 4S should I stick with AT&T or go with Verizon or Sprint.
